MODEL 1517
SentriVoice

INTRODUCTION

SentriMax is a powerful full-featured, industrial voice and page alarm system. Users can monitor and control up to 64 digital inputs/outputs and 8 analog inputs via telephone or radio. Upon sensing an alarm condition, SentriMax automatically alarms through a user programmable list of phone or radio sources with specific user recordable voice messages stored in solid state memory or optional alphanumeric text messages. This provides a friendly interface that doesn�t require special training for system operation.

The SentriMax comes in a rugged, waterproof NEMA 4X fiberglass case with integrated battery backed operation for reliable performance. Conventional and trunked mobile type radios and cell-phones can be easily mounted within the SentriMax enclosure. The SentriMax has been carefully designed for easy installation and setup. Programming can be done via a PC running the included configuration program, over the phone with DTMF or from the keypad on the front panel.

Expandable Digital Inputs/Outputs

The SentriMax comes standard with 16 digital inputs that may be user programmable as outputs for control purposes. Up to three additional 16 digital input/output expansion cards may be added to an individual unit giving a total capacity of 64 digital inputs/outputs.

Pulse Counters

The first 16 digital I/Os have the ability to keep track of the number of alarm events detected on that input. If the input is set up as normally open, a transition from high to low causes the counter to increase by one, but a transition from low to high does not. For example, this can be used with a water meter that outputs a pulse every 10,000 gallons of water that flows through a pipeline. The counter allows the user to keep track of the total flow through the pipeline and alarm when the flow reaches a programmable level.

Run Time Recording and Alerting

The first 16 digital I/Os can be used as run time meters that keep track of the total time the input is in an alarm condition. The run time meters can accumulate up to 999 hours and 59 minutes. For instance, a pump may need to be serviced every 200 hours of use. The run time metering capability of the SentriMax allows you to keep track of the in-use time of the pump and alarm the user when it�s time for service.

Scalable Analog Inputs

SentriMax comes equipped in the standard unit with 8 analog inputs. These analog inputs allow SentriMax to alarm according to changes in flow, temperature, pressure etc. The SentriMax directly supports transducers with 0 to 5 Volt or 4 to 20 mA outputs. The values of the transducers may be scaled according to the application. For example, a water level sensor might output 0 Volts when the water tank level is at 5 feet, and 5 Volts when the level is at 80 feet. SentriMax can
alarm and report according to the values being monitored.

Remote Control and Status Inquiry

Users can access the SentriMax via telephone or radio equipped with a DTMF pad to control outputs connected to the system. The current status of an alarm or the status of an input is also available by accessing the system. Responses to status inquiries can range from the standard factory prerecorded voice messages to customized user recordable status messages. Users can choose to use a default message such as �digital input 1 ON� with the standard factory voice prompts or record �lower bay door open� with the user recordable prompts.

System Monitor Alarms

SentriMax features these additional system alarms that can help ensure worker safety and verify proper operation. A panic button is provided on the front panel of the SentriMax that can be used to summon help to a site in the event of an emergency. Discrete alarms for AC Power Loss, Low Battery condition and Internal High Temperature are included in the standard unit. An �All�s Well� message can be enabled so that the SentriMax periodically notifies a list of people that the system is properly functioning.
